Improve status of predictions with field coloring

[lazygalaxy]

Would be nice to indicate the status of a prediction by coloring the background of the input field. For example:

a. Green when valid prediction was saved

b. Red on invalid prediction (not saved)

c. White no prediction yet

d. Gray: field locked because game is running or finished or field s not open for entry yet

We would like to have all predictions still available via this menu (competition selectable), even if the tournement has started but is not completely finished. If it is too late to change, the prediction input dialogue should be grayed out, as mentioned earlier. This way we assume the navigation is easier to understand for the users.
